Maintenance and Troubleshooting

Identifying the Left and Right Polarizers: Although the left and right polarizers have very different optical characteristics, they appear to be identical. As a result, once you remove them from the projector it may be difficult to tell them apart. Use the following technique to verify which one is which:

1.Place the polarizer on a clean, smooth, flat surface with the side that faces the projector facing up.

2.Hold a pair of 3D glasses above the polarizer as shown here:

	Left Polarizer*		3D Glasses	Left Polarizer*
Same Angle of	L	R	L	R
Polarization
(light passes)

Different Angles of Polarization (light does not pass)

572-2479-00REV00 572-2479-00REV00

*viewed from the side facing the projector

3.If the right lens on the glasses turns black when it is above the polarizer, this tells you that the polarizer came from the left-eye optical engine on the projector.
